I had a G400 SH on my CAD machine until yesterday when I brought home a GeForce DDR. I haven't played any games on the DDR yet, sold off my UT and Q3 early this week, but before I left home I dl'd the demo for MDK2. So tonight I am going to fire that up and see what happens. I am going to put the G400 on a Celeron2 machine that I think I am going to make my main CAD station. The 2d on the G400 is awesome. I would have gone with the DH, but since I only have one monitor at the moment and when I can afford another one, I will set up both machines in different rooms I didn't think I would use the DH feature. Of course the TV out would have been nice.
